UltraDNS provides several key features to boost email security:
DNSSEC (Domain Name System Security Extensions): This adds an extra layer of security by authenticating the origin of DNS data, reducing the risk of attacks such as cache poisoning. DDoS Protection: UltraDNS mitigates distributed denial-of-service attacks, ensuring your DNS remains available and your emails are not disrupted. IP Filtering: This allows you to create whitelists and blacklists to control which IP addresses can interact with your DNS, enhancing security.
